You can put this solution on YOUR website! after flying at an altitude of 500 meters , a helicopter starts to descend wheni it ground distance fron the landing pad is 11 kilometers . What is the angle of depression?
-------------
500 meters is (1/2) km
------------------------
Draw the picture: The height is (1/2)km ; the length is 11 km.
The angle of depression = inversetan[(1/2)/11] = inversetan(1/22) = 2.6 degrees
